Multifunctional lightning protection module

Abstract

The invention provides a multifunctional lightning protection module, which comprises an outer cover provided with a deterioration indication window, wherein the inside of the outer cover is provided with a lightning protection circuit comprising a lightning protection device, an inserting piece, a releasing piece and a connecting piece and a support of a deterioration indication device; the lightning protection device comprises a voltage dependent resistor and a discharge tube; the releasing piece is in electric connection with the inserting piece; the support is formed by connecting a left support and a right support; the cross sections of the left support and the right support are I-shaped; the voltage dependent resistor is arranged on the outer sides of the left support and the right support; an overheat protection and overcurrent protection device is arranged on the inner sides of the left support and the right support; the deterioration indication device is arranged on the top parts of the left support and the right support; the inserting piece of which the inside is connected with the lightning protection device and the outside is connected with a lightning protection base is arranged on the bottom parts of the left support and the right support; the lightning protection circuit is selected to be one of a Y-shaped mode circuit, a transverse protection mode circuit, a 'one plus one' mode protection circuit, a parallel connection combination transverse protection mode circuit, a 'two plus zero' mode circuit and a 'Kelvin' wiring mode circuit; in the same lightning protection module structure, different lightning protection circuits can be combined respectively, so that the one-module multi-purpose is realized; and in the module, any nonlinear element (the voltage dependent resistor) is provided with an overheating release protection device.

Description

technical field [0001] The invention relates to a lightning protection module, in particular to a multipurpose lightning protection module for power supply. Different lightning protection circuits can be combined in the same lightning protection module structure to realize multiple functions of one module. Background technique [0002] At present, the generally used power supply lightning protection module structure can only combine one kind of lightning protection circuit, and each module of the SPD formed by it can only realize one protection mode. If a different protection circuit needs to be installed, a different structure is required to realize it. In this way, it not only increases the development cost, but also increases the variety of products, which brings inconvenience to various production links such as material management, production management, and quality management, and at the same time increases production and management costs. As we all know, the lightnin...
